Isabella Allen from the Australian Securities and Investments Commission led the formal investigation from September 8, 2020, into Ms Caddick's Ponzi scheme operated under her fake company Maliver.
The conwoman purported to be investing her victims' wealth by appearing to set up CommSec trading accounts and forging documents to claim she was generating profits through capital growth and shares.
She preyed on mostly friends and family, and stole up to $30 million between 2013 and 2020, counsel assisting Jason Downing SC has told the inquest.
Meanwhile, Ms Caddick's luxurious five-bedroom, four-bathroom eastern suburbs home has come on the market, the prime asset in the estate of Caddick, 49, who disappeared on November 12, 2020.
The Dover Heights mansion boasts uninterrupted and expansive views of Sydney Harbour and a "stunning pool", which receivers hope will fetch at least $10 million.
Bruce Gleeson from Jones Partners, the receivers of Melissa Caddick and liquidators of Maliver Pty Ltd said the sale campaign would be conducted via an expressions of interest until October 31.
"We are also well advanced and close to finalising an application to the Federal Court which will seek sale orders regarding the designer jewellery, clothing and artworks," Mr Gleeson said in a statement on Monday.
A week after the corporate watchdog began its investigation into the misappropriation of funds, Ms Caddick booked document shredding services at her home address.
The last verified sighting of Ms Caddick was when ASIC and the Australian Federal Police raided her Dover Heights mansion on November 11, 2020.
Ms Caddick's mother Barbara Grimley holds ASIC responsible for her daughter's suspected death, saying she was highly distressed during the raid and was not allowed any food or water.
The AFP's Constable Amelia Griffen shadowed Ms Caddick for the majority of the 12-hour search and confirmed she did make herself food and was allowed to leave the property whenever she wished.
Her husband Anthony Koletti reported the 49-year-old as missing some 30 hours after he says she walked out of their home for the last time on November 12 about 5.30am to "go for a jog".
Mr Koletti is due to give evidence following Ms Allen.
What Mr Koletti knew about Ms Caddick's disappearance was scrutinised in the first week of his wife's inquest.
The part-time hairdresser and DJ told police he was too busy working from home to make a statement in person. Police subsequently visited him at home, where he gave "conflicting stories", Sergeant Trent Riley told the coroner.
In February 2021 Ms Caddick's decomposing foot encased in an Asics shoe washed ashore at Bournda Beach on the NSW south coast, about 400km south of Sydney.
The inquest before Deputy State Coroner Elizabeth Ryan will resume on Monday after a week's break.
